When Berta hurts her back, Walden and Alan start looking for another housekeeper.
"Two and a Half Men" was originally about a hedonistic jingle writer, Charlie Harper; his uptight brother, Alan; and Alan's growing son, Jake. Charlie's free-wheeling life is complicated when his brother gets divorced and moves, along with his son, into Charlie's beach-front Malibu house.
The series' premise was revamped in the ninth season, focusing on Alan moving on with his life after the death of Charlie with help from his new best friend and roommate, Walden Schmidt, who is also dealing with his own troubles following a bad divorce. Alan, Walden, and Jake eventually bond, becoming close friends, forming a surrogate family unit.
